The warning sign of "07" license plate style change is Pinyin. Compared with the "99" license plate, the "07" license plate of the Armed Police has obvious differences in style. Its main characteristics are: the composition of the number plate breaks the traditional pattern, the character specifications change from equal size to large and miscellaneous structure, and the spacer is replaced by pattern; The car number plate is completely distinguished from the cart number plate; The warning signal was changed from Chinese characters to pinyin letters. The number plate consists of the "WJ" sign of the Armed Police, the badge sign, the code of the issuing authority, the police type sign, the code of the directly affiliated unit and the serial number. Gold troops are H, forest troops are S, hydropower troops are D, traffic troops are T, border troops are B, fire troops are X, and security forces are J. Enhance anti-counterfeiting function, increase chip information and increase number plate capacity. The unit codes of gold, forest, water and electricity, traffic troops, frontier defense, fire fighting and security forces (frontier inspection station and local security office) are composed of 26 English letters, and the starting and ending arrangement numbers of vehicle unit codes are A00 1-Z999. For the first time, the number plate adopts the international advanced design watermark hot stamping and thermal transfer production technology, and the service time can be as long as 10 years. License plate anti-counterfeiting technology is more advanced. On the basis of physical anti-counterfeiting and hidden color anti-counterfeiting, the chip information anti-counterfeiting technology is added. The chip can store more than a dozen pieces of related information, such as license plate number, engine number, chassis number, vehicle license plate number, driver's name, vehicle unit, etc. , and can be identified by hand-held readers. The number plate adopts international advanced production technology and anti-counterfeiting technology for the first time. On the one hand, we can directly identify the authenticity of the number plate by visual inspection of color patterns, anti-counterfeiting marks, digital characters and the fineness of the appearance of the number plate. On the other hand, we can also read the radio frequency chip for identification and obtain the vehicle information stored in the chip to realize supervision. In the production of certificates, thermal sublimation printing is used to realize the instant printing of personnel and vehicle information, photos and seals; Personnel photo collection and editing adopts the image processing technology of "second-generation ID card", which is convenient and quick to input.
